To all/whom t may cof/wem:

Be it known that I, WILLIAM E. PHILIrs, a citizen of the United States,'residing at. Cleveland, in the county of Cuyahoga and State of hiO, have invented a certaln new' and useful Improvement in Belt-Conveyer Supports, of which the following is a full,

clear, land exact description, reference being'` had-to the accompanying drawings.

My invention relates to a conveyer support and has for one object to provide a support having movable parts so arranged as to be properly lubricated at all times and 4kept free from dirt and grit.` v

More specifically an object of the invention is to provide a means for constantly and continuously feeding lubricant fory a long period of time to the bearings of the movable parts of the support without attention from the attendant. ,f

Another object is provision of a. support so arranged as to prevent accumulation ot" dirt and grit adjacent the bearings.

It will be seen that by employing the continuous lubricant feed together with the arrangement for preventing the accumulation of dirt adjacent the bearings, that the bearings are ke t properly lubricated and tected at all) times, the inner feed. contlnuously forcing fresh lubricant to the bearings and driving out and preventing the acclr` mulation of any dirt.

Further objects of the invention will bc apparentin the course of the following description and the features of novelty will be set forth in the claims. l

In the drawings-in wshicha devlce embodying the principles of my invention is' illustrated, F 1g. 1 is a sectional viewtaken transversely to the conveyer beltg. Fig.l 2 is a fragmentary side elevation of the. fle-. vice; Fig. 3 is a sectional View taken sub` stantially along the line 3-3of Fig. 1; Fig.

' 4' is a fragmentary longitudinal section'on an enlarged scale through one 4of the belt supporting rollers and adjacent supporting means..

The construction illustrated comprises a suitablel frame work for carryin the belt supporting rolls with a conveyer elt thereon. This frame 'Work consists ofsets of' standards-10 arranged adjacent the sides of the belt and carrying at their upper ends beams 11 which are suitably secured theretp and eitend along the run yof the belt and ing members 12 which are herein shown as 'provided with the upper ii-shaped flanges 13 for supporting angle irons or bars 20. These angle irons are`preferab1y made of such'. form as to prevent the accumulation of dlrt upon their upper surfaces and are herein shown as tl-formed, having the apex o f the V u ward. These members are deslgned t0` orma support for the rolls of the conveyer belt and may be bent lon tudinally to conform approximately to t e shape in'which the belt is held transversely.

As the bars 20 are bent so as to c0nform approximately to the trough shape of the conveyer, 'thestandards 21 may beI short members so that the bar 2O serves to rmlv hold the rolls -22 in proper position. In order to more fully support these bars as Well as to brace the side vframe structure, l provide a 'pair of cross-bars 33 corresponding to each of the angle members 20. These` cross-bars are situated at the sides of their respective angle members and are connected at their ends to the standards v10.

they occupy a horizontal height ,substan.

tially the same. as thatofthe' bars 20,' a'v connecting member 3,4 being emplo ed nt.'

this point. stantially the shape of a W incross-section and its side anges are connected respectivelyl tothe bars 33, while its centralportion-approximately conforms to and is sefcured tothe angle member 20, as is clearly lshown in Fig.v3. In the case of conveyers of this type, it

is essential that the bearings of the several rolls shallbe efficiently lubricated and protected against access of dirt. The form of This member as shown 1s Subsupportnigfframe above described revents the accumulation of dirt adjacent t e bearin and in order to further insure this resuts, provide a system of self feed' lubrication which will operate to furnish fresh lubricant to the bearings so as to force out dirt from the bearings andv operative for a long period of time without the `attention of the operator. 1

As herein shown, each of the belt supporting rolls. 22 is a Wheelv having an internal by each roll may be rotatably mounted on a tubular member 23 of smaller diameter, such members extending outwardly through openings in the wheel whereby they may be supported partially. Suitable bearings 25, between these bushings'may be employed whereby 'each roll is rotatably mounted on the corresponding tube 23 which constitutes a stationary axle with a space between the.

tubes 23 and 2li.

'lhe tubes 23 are supported by means oi brackets or standards 21, which are secured at their'lower ends on the angle irons 20..

These standards have transverse openings 26 through their upper ends shown as being enlarged' at their ends to receive the ends oi the tubular members 23 with a tight t, the ends of the tubes 23 abuttin the shoulder formed bythe enlargement w ereby a sealed connection is formed and a continuous passageway, extending axially through the cen-- ter ci the rolls 22, is provided.

`The tubularmembers 23, are provided with suitable lateral openings 2'?, providing communication through this central passageway" to the bearings and also to the space intermediate the members 23 and 24:. ln order to provide a continuous dirt tree feed oi -lubricant l prefer to provide within this space, a member adapted to maintain pressure upon the lubricant and herein shown as'consisting oi a cup-shaped annu? lar metal member 30 and having a spring Si bearing against it. Such. feed may be provided associated with. any or all of the rolls as desired, though it is believed to be preferable to have it applied to the lower roll and to any ot the others as desired. @n the end standards 2l, there may be provided suitable check valve connections 32 of standard form having communication to the central passageway and means., fonat'm4 taching a lubricant conduit whereby lubricantinay be forced to thecentral passage way, and iii desired, similar connections may be provided on each of the intermediate' standards or uprights 21`as herein shown.

llt will be apparent that when the lubricant is Jbreed into the central passageway through any or all of these inlets, that the grease will force back the member or menibers 30 against the action of their springs and thereupon the springs will act to main-- tain pressure in the grease so as to insure its being ted to the several .bearin By this means, the proper feed of lubricant, to the bearings of the upper rolls as well as to those of lower rolls will be insuredo rlhis construction obviates the diculties which have been experienced in the past, of

' a failure to lubricate the bearings on. the

.lubricant to the space through the sacarse lindrical members are preferably provided with cupped portions adapted to receive the ends of the tube.

ln order to support the return run of the belt 40, suitable 'rolls 35 may be journaled in the standards 10 as shown.

lt will be apparent that l have provided a means whereby the rollers are continuously lubricated without attention from the operator and are also protected against dirt and grit. The V-shaped angle bars will preventY any accumulation of dirt which might otherwise rise to a height suiiicient to come into contact with the-rollers and their bearings. lt should be noted, however, that this angle` bar construction is not clair-fied herein, but in my co-pending application No. 557,468 led April 29, 1922.
